The Lahn Bridge in Balduinstein is the only road bridge over the Lahn in Balduinstein , a local community in the Rhein-Lahn district in Rhineland-Palatinate .
The next road bridges are upstream in Diez, six kilometers away, and downriver in Laurenburg, thirteen kilometers away .
The bridge was the first prestressed concrete bridge to be erected using a cantilever .
description
The bridge is a 62 meter wide haunched, two- legged T -beam bridge made of prestressed concrete . It was designed by Ulrich Finsterwalder and built by Dyckerhoff & Widmann according to their Dywidag system with counterweights behind the abutments.
It was cantilevered from both sides in concreting sections of 3 meters each and anchored with the tie rods developed by Finsterwalder, which had a special thread for anchoring and which could be extended as required using sleeves.
The bridge has since become decrepit. The permissible total weight for road traffic was limited to 12 tons. Investigations have shown that the bridge cannot be renovated, which is why a new bridge is to be built a few meters upstream and the old one is to be demolished afterwards.
history
The bridge replaced an iron truss arch bridge from 1903, which was destroyed by the Wehrmacht shortly before the end of World War II in March 1945 in order to delay the advance of American troops. Martin Heil from Balduinstein provided a ferry service until the new bridge was put into operation on April 25, 1951. The statue The Last Ferryman from Balduinstein , which was erected on the bridge in 1953, reminds us of this.
